Primerica?

just woundering if anyone knows anything about this. i've been approached by 2 diffrent people now while shopping at walmart. they both had a similar spiels, but neither one would acually tell me what they were trying to do unless i agreed to meet with them. wich i didnt. they ask me if i am looking for work (i dont know i guess i look homeless j/k), but i say sorry i do have a full time job. the last "couple" introduced me to his fiance as they pushed around their cart full of stuff. so after words i get my car loaded up and i'm sitting there getting ready to back out and guess who walks out of walmart with nothing. the happy couple. i wounderd what happend to all the stuff they had in their cart. anyways that last part was a little off subject, but this whole thing just seems like a scam or a pyramid schem of some sort. the reason i believe that is due to the shadyness of the people trying to "sell" me on their pitch. if anyone could enlighten me i would appriciate it. thanks.
